Abstract

Many real-world domains present the problem of imbalanced data sets, where examples of one class significantly outnumber examples of other classes. This situation makes learning difficult, as learning algorithms based on optimizing accuracy over all training examples will tend to classify all examples as belonging to the majority class. In this paper we introduce a method for learning from imbalanced data sets which is composed of three algorithms. Our experimental results show that our method performs accurate classification in the presence of significant class imbalance and using small training sets.
